  • Soil and nutrient management.
  • Past research concentrated on nitrogen management in irrigated and dryland systems (conventional and no-till) and limited irrigation no-till cropping systems.
  • Current research efforts focus on soil and fertilizer management to improve crop production efficiency for major and minor crops in western Nebraska (corn, dry beans, winter wheat, brassicas, sugar beets, chicory) including research on limited irrigation no-till cropping systems.
  • Other research interests include manure management.


Research and extension efforts to improve crop yields through improved nutrient management on high pH western NE soils including manure management. Major emphasis will be working with the PHREC team on adapting cropping systems to limited surface and subsurface irrigation supplies for the future.


  • Current efforts focus on soil and fertilizer management to improve crop production efficiency for major and minor crops in western Nebraska
  • Interests in soil salinity management and irrigation water quality
  • Leading a major demonstration project on limited irrigation no-till conservation cropping systems in the Pumpkin Creek Watershed
  • Comprehensive Nutrient Management Planning and manure management
